Replacing CAT 303.5 tracks involves safely preparing the machine, releasing track tension, removing old tracks, installing new ones, and adjusting tension for optimal performance. This process preserves safety and extends undercarriage life, with parts available for purchase online from trusted Canadian suppliers like AFT Parts offering deals, best prices, and free shipping.
How Do You Safely Prepare a CAT 303.5 Excavator for Track Replacement?
Begin by parking the excavator on firm, level ground and turning off the engine. Engage the parking brake and chock the wheels or tracks to prevent movement. Use suitable lifting equipment or the boom and blade to raise the track off the ground, stabilizing the machine with cribbing for a safe working environment.
What Tools Are Needed to Replace CAT 303.5 Tracks?
Essential tools include a grease gun, pry bar (chisel bar), a 19mm open-end wrench or ratchet for grease fittings, and a suitable lifting device or blade for raising the machine. Personal protective equipment such as gloves, steel-toe boots, and safety glasses is crucial for operator safety.
How Do You Release Track Tension on a CAT 303.5?
Locate the grease fitting (zerk fitting) on the track tensioner. Using a wrench, turn the grease fitting counterclockwise to release the tension, allowing the track idler to move inward and loosen the track, making removal possible. Remove the grease valve completely if necessary for maximum track slack.
How Is the Old Track Removed from the CAT 303.5?
With the track loose, insert a pry bar between the sprocket and the track to create space. Have an operator slowly drive the track forward or backward to ease the track off the front idler. Always maintain a safe distance and use controlled force to prevent injury or damage.
How Do You Properly Install New Tracks on a CAT 303.5?
Position the new track with the 'V' pattern facing forward, aligning it with the sprocket and carrier rollers. Using the lifting device and operator control, guide the track onto the sprocket and rollers gradually. Employ a pry bar to assist if necessary, ensuring all track links engage correctly without pinch points.
How Do You Adjust Track Tension After Installation?
Reinstall the grease fitting on the track tensioner and pump grease gradually to push the idler outward, tightening the track. Check manufacturer-recommended sag between the track and carrier rollers—typically about one inch. After initial tensioning, run the track forward and backward to settle it, then recheck and adjust tension as needed.
